Description

An instrument for measuring the angle of rotation of the torso

technical field

The utility model relates to the field of instruments and meters, in particular to a trunk rotation angle measuring instrument.

Background technique

Nowadays, the pace of life is getting faster and faster, and people are paying more and more attention to their physical health. An important part of measuring physical health is body flexibility. Body flexibility can characterize the range of motion of human joints and the elasticity and stretchability of ligaments, tendons, muscles, skin and their tissues across joints. Body flexibility has local characteristics, and is usually evaluated by the range of motion of joints. The measurement methods and means involve the joints of relevant parts of the body, such as the measurement of a single joint or a single part, or the measurement of several joints or parts simultaneous measurements. Trunk flexibility is an important aspect of body flexibility. Its range of motion in the sagittal plane can be measured by sitting and forward flexion, and its range of motion in the horizontal plane can be measured by trunk rotation angle. When people have a full understanding of their body flexibility, they can carry out targeted exercises in a timely manner according to the actual state of the body to enhance their physical fitness.

Current measurements of torso rotation angles rely on a wooden stick attached to a tapered weight. The specific measurement method is: draw a picture of 0°-180° on a flat ground, stand with both feet apart at a certain distance, stand on a straight line of 0°-180°, bend the elbows behind the body and clamp the A wooden stick with a conical weight, so that the tip of the cone is facing 0°, slowly rotate to the left and right twice, and take the rotation angle as the measurement value.

This measurement method has high requirements on the standardization of the action of the measured person, it is difficult to use a unified standard to give a more accurate measurement value, and the accuracy of the measurement result is not high.
